My body has basically had a good yell at me saying I need a deload week, so I will obey. I suppose the question is how my body yells at me, and it's just something I can feel. It just feels beat up. I've been also getting little injuries like pulling some muscle in my neck and another in my left wrist.
I don't recall exactly when my last deload was, but I get the impression it was in June sometime. So it's overdue. I think to avoid problems like this in the future I should put this into my todo app on my phone as a recurring thing to do every 10-12 weeks - just to be ahead of problems.
I had a proper workout on Monday, so the deload will be Wednesday, Friday and Monday's workouts. The plan is a light volume workout.
